walking fish

Definitions

from the GNU version of the Collaborative International Dictionary of English

any one of numerous species of Asiatic fishes of the genus Ophiocephalus, some of which, as Ophiocephalus marulius, become over four feet long. They have a special cavity over the gills lined with a membrane adapted to retain moisture to aid in respiration, and are thus able to travel considerable distances over the land at night, whence the name. They construct a curious nest for their young. Called also langya.
